Question #14 - I'm not really sure how to figure out the right answer with the given constraints and information from the question. From glancing at the question, it seems like choices A, B, C, and D are all plausible answers?

Hey cfu1, welcome aboard! From your question, I am guessing that there may be a small problem with your setup. Would you mind describing what you diagrammed for the original set of rules? From there we can do a better job of diagnosing the problem.

Meanwhile, consider this: the rules tell us that house 6 is an S, and they also tell us that ever R has to have at least one T next to it. Be careful here - "adjacent" does not mean the same as "facing" (I bet that's where things went sideways on you!) House 8 is adjacent to house 6, and not adjacent to any other house (house 7 faces house 8, but is not adjacent to it). Knowing that much, without even getting into this specific question, we know for sure that house 8 cannot be an R, because every R must have a T next to it on one side or the other or both. Answer A not only cannot be true in this case, it can never be true!

Share with us your original diagram, and then tell us whether the info I just provided changes anything in your analysis. From there, we'll see where we can go together!

Talk to you soon.

Ahh, here's my starting diagram:
  • ..... ..... S
    2 ..... 4 ..... 6 ..... 8

    1 ..... 3 ..... 5 ..... 7
    ..... R
Going back and rereading the question, in order to satisfy the condition of the question, I realized that R must be numbers 3 and 4, because as you mentioned before, if R is 8, the condition "every R has at least one T adjacent to it" cannot be satisfied.

So the only possible set-up with this question is:

  • T ..... R ..... S ..... T
    2 ..... 4 ..... 6 ..... 8

    1 ..... 3 ..... 5 ..... 7
    T ..... R ..... T ..... S
Which means (B) is the correct answer.

Haha I feel kinda dumb. I think I was missing bits and pieces of each condition, which was why I couldn't figure out the correct answer.

Thanks for your help and guidance!!

You're welcome! I do think your local setup has some unwarranted info in it, but you still got the right answer as a result. It looks to me like house 1 can be an S or a T, and house 7 can be an R or an S. Check those against the rules and see if they work for you! You want to do as much as you need to on these local questions, but don't box yourself in with inferences that are not required. With your diagram, if the correct answer was "house 7 is a ranch" it would have looked bad to you, and then where would you be?

Nice job getting past that problem! Keep up the good work!
